What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Bacterial meningitis remains a very important disease worldwide, and the major causative pathogens were Neisseria meningitidis (N. meningitidis), Streptococcus pneumoniae (S. pneumoniae) and Haemophilus influenzae (H. influenzae). In our context, the technical difficulties encountered in the routine practice were associated with the fragility of these bacteria, the high rates of negative culture and the demanding transport conditions. That's why the need to look for a solution to its technical problems and to propose a new proper solution with the local situation. The aim of this study was to develop, perform and evaluate a novel biphasic medium used for the transport, culture and conservation at an ambient temperature of N. meningitidis, S. pneumoniae and H. influenzae. The results showed that this biphasic medium provided more, novels and easy nutriments through the addition of liquid phase and solid phase medium and it was found to be conducive to the growth and conservation of N. meningitidis, S. pneumoniae and H. influenzae at an ambient temperature of a minimum of 40 days. And the ingredients used in the medium are readily available at a low cost as well as the components prepared in large quantities, they could be stored at + 4 ± 1 °C for 2 years without significantly altering their growth and conservation supporting their potential. The survival and recovery for the fastidious bacteria on the biphasic medium and the other media used for comparison in this study were significantly different (P < 0.05). In addition, the Sensitivity, Specificity, Positive and Negative Predictive Value of biphasic medium showed highest among the three bacteria at least 40 days of storage at room temperature in this study. In conclusion, we found the biphasic medium to be low cost and suitable for previously mentioned bacteria from suspected meningitis patients, offering an optimal condition and an increase in the viability of the isolates at ambient temperature. And it was concluded that this biphasic medium could be used as a technical solution in laboratories for the management of meningitis.
